Final answer:
To find the current (I) using Ohm's Law where V=IR, rearrange the equation to I=V/R. Therefore, the correct answer is A. I = V/R.
Step-by-step explanation:
The original equation given by Ohm's Law is V = IR, where V represents the voltage across a resistor, I represents the current flowing through the resistor, and R represents the resistance. To solve for the current (I) in terms of the voltage (V), you would rearrange the equation to isolate I. This yields the equation I = V/R, where you divide the voltage by the resistance to get the current. Thus, the correct answer to the question is A. I = V/R.
